Filtered == Port is blocked by a firewall. (As said below :))If you want more information, it is available in the nmap man page (run the command 'man nmap' at the prompt), or the nmap web site, which is at http://www.insecure.org/nmap.

A port is in either of the two states ie , open or closed at any point of time. But using a firewall a particular port can be blocked.In such a scenario when nmap is run aganist a system which has a particular port blocked by a firewall , then the nmap result will show that the particular port as filtered . Normally nmap will show only two types of output ie the open and the filtered ports , the closed ports are not shown .
